Monograph of Thysananthus subgenus Thysananthus (Lejeuneaceae, Marchantiophyta)

FURTHER NAMES IN THYSANANTHUS

Thysananthus africanus (Sim) S. Arnell, Bot. Not.: 282. 1953, nom. illeg. [Art. 53.1]

Thysanolejeunea africana Sim, Trans. Roy. Soc. South Africa 15: 50. 1926.—Type:

South Africa. “Perie forest, Kaffraria”, Sim 346 (not seen). Wigginton & Grolle (1996) mentioned: “To be clarified. Collected only once?”.

Thysananthus erosus Steph., Sp. Hepat. 6: 568. 1924.—Type: NEW GUINEA. “Ledermann s.n.” (not seen); Icon. Steph. nr. 10180 = Conoscyphus Mitt.? Verdoorn (1934) considered T. erosus as a member of Jungermannieae. Judging from the original description and the drawing of T. erosus of Stephani’s “Icones Hepaticarum Ineditae”, which shows one leaf and one underleaf, this might be Conoscyphus.

Thysananthus frauenfeldii Reichardt, Verh. K. K. Zool.-Bot. Ges. Wien 16: 958. 1866.

Mastigolejeunea frauenfeldii (Reichardt) Verd., Blumea 1: 230. 1934.—Type: TAHITI. Novara Exped., “…um Papiete, Jelineck s.n.” (not seen).

153 Thysananthus fruticosus fo. pendula Herzog, Trans. Brit. Bryol. Soc. 1: 319.1950, nom. inval.

[Art 32.1(d)]. Material: MALAYSIA. Sarawak: “Dulit, … n. 2277”, 1932, P. W.

Richards s.n. (not seen).

Thysananthus hebridensis Steph., in Stephani & Watts, J. & Proc. Roy. Soc. New South Wales 48: 134. 1914, nom. inval. [Art 32.1(d)]. Material: VANUATU [“New Hebrides”]. Tafea: Aneityum, Gunn s.n. (not seen).

Thysananthus integerrimus Steph., Sp. Hepat. 6: 567. 1924.—Type: NEW GUINEA.

“Ledermann s.n.” (not seen); Icon. Steph. nr. 10187. Verdoorn (1934) considered T.

integerrimus as a member of Jungermannieae.

Thysananthus lacerostipulus Steph., Sp. Hepat. 6: 567. 1924.—Type: NEW GUINEA. Ledermann s.n. (not seen); Icon. Steph. nr. 10223 = Conoscyphus Mitt. ? Verdoorn (1934) considered T. lacerostipulus as a member of Jungermanieae. Judging from the original description and the drawing of T. lacerostipulus of Stephani’s “Icones Hepaticarum Ineditae”, which shows one leaf and one underleaf, this might be Conoscyphus.

Thysananthus polymorphus var. β planifolia (Sande Lac.) Schiffn., Consp. Hep. Archip. Ind.:

305. 1898. Phragmicoma polymorphua fo. β planifolia Sande Lac., Syn. Hepat. Jav.:

58. 1856.—Type: INDONESIA. Java: “ad montem Salak, Zollinger, coll. sub 3560 (pl.

femina); Herb. v. d. Bosch (pl. mascula)” (not seen).

Thysananthus ungulatus (Mitt.) Steph., Sp. Hepat. 6: 567. 1924. Lejeunea ungulata Mitt., J.

Proc. Linn. Soc., Bot. 5: 110. 1861.—Type: BURMA. “in Pegu, ad Rangoon,…”, McClelland s.n. (not seen) = Spruceanthus Verd.? Verdoorn (1934) doubtfully referred T. ungulatus to Spruceanthus (“cf. sub Spruceanthus”). Judging from the original description, this might indeed be Spruceanthus.

154 Thysananthus wardianus (Mitt.) Verd. (“Steph.”), Ann Bryol., Suppl. 4: 166. 1934 as in Index Hepaticarum (Geissler & Bischler, 1990). Lejeunea wardiana Mitt., J. Proc. Linn.

Soc., Bot. 5: 109. 1861.—Type:INDIA.“in Assam superiore”, Griffith s.n. (not seen) = Thysananthus subg. Mastigolejeunea (Spruce) comb. nov., syn. fide Verdoorn (1934): 166.
